Cardiovascular diseases (CVD) are the leading cause of death worldwide. Mesenchymal Stem Cell (MSC) therapy is an alternative for patients who cannot recover with current treatments. Ensure movilization of MSC to the affected organs would represent an advantage for therapeutic management of CVD. Dehydroepiandrosterone (DHEA) is a hormone precursor whose levels decrease throughout life, which has been associated with the onset of CVD. Several studies have shown that DHEA consumption, prevents and improves heart condition, although it is not known if this is because an effect on cardiomyocytes is exercised on these cells and this, in turn, to CTM. The aim of this study was to determine the effect of conditioned medium from H9C2 cell line pretreated with DHEA and subjected to damage, on the motility of CTM, performing a wound healing assay. Pretreatment with DHEA and damage to H9C2 cell line, promotes motility of CTM. Stimulation of CTM motility by an indirect effect of DHEA could be a therapeutic strategy for heart damage.

AbstractObjectivesWound healing is a complex process with a sequence of restoring and inhibition events such as cell proliferation, differentiation, migration as well as adhesion. Mesenchymal stem cells (MSC) derived conditioned medium (CM) has potent therapeutic functions and promotes cell proliferation, anti-oxidant, immunosuppressive, and anti-apoptotic effects. The main aim of this research is to study the role of human umbilical cord-mesenchymal stem cells (UC-MSCs) derived CM in stimulating the proliferation of human keratinocytes (HaCaT).MethodsFirstly, MSC were isolated from human umbilical cords (UC) and the cells were then cultured in proliferative medium. We prepared and collected the CM after 72 h. Morphological changes were observed after the treatment of HaCaT cells with CM. To validate the findings, proliferation rate, clonal efficiency and also gene expression studies were performed.ResultsIncreased proliferation rate was observed and confirmed with the expression of Proliferating Cell Nuclear Antigen (PCNA) after treatment with HaCaT cells. Cell-cell strap formation was also observed when HaCaT cells were treated with CM for a period of 5–6 days which was confirmed by the increased expression of Collagen Type 1 Alpha 1 chain (Col1A1).ConclusionsOur results from present study depicts that the secretory components in the CM might play a significant role by interacting with keratinocytes to promote proliferation and migration. Thus, the CM stimulates cellular proliferation, epithelialization and migration of skin cells which might be the future promising application in wound healing.

Objective: In this study, the embryonic rat cardiomyocyte cell line H9C2 was used to investigate the cardiotoxicity effect of sappan wood ethanol extract (SWEE). Methods: Sappan wood was extracted in 96% ethanol and divided into dose concentrations of 2.5, 5, 10, 50, 100, and 150 μg/ml, with deferiprone used as a control. Cell viability was assessed using the PrestoBlue Cell Viability Reagent, according to manufacturer protocols. Results: Microscopic examination showed that the cell viability of H9C2 was preserved by SWEE treatments at a dose of 10 μg/ml and suggested dose concentrations of 50 μg/ml of SWEE. The percentage of viable cells was greater than 95% with a dose concentration of 10 μg/ml of SWEE, but it was significantly reduced with a dose concentration of 50 μg/ml of SWEE (p<0.05). Conclusion: The optimal dose concentration of SWEE to reach 95% cell viability was 10 μg/ml.

Abstract To investigate potential prevention or attenuation of anti- cancer drug induced cardiotoxicity using anti-ischemic drugs, a rat myoblast (H9c2) cell line was used as our in vitro cardiac model. Irinotecan and doxorubicin were found to be cytotoxic for the H9c2 cell line with IC50 of 30.69 ± 6.20 and 20.94 ± 6.05 mmol L-1, respectively. 5-Flurouracil and cladribine were not cytotoxic and thus IC50 could not be calculated. When 100 mmol L-1 doxorubicin was incubated for 72 hours with 50 mmol L-1 diltiazem, 100 mmol L-1 dexrazoxane and 100 mmol L-1 losartan, respectively, there was a 58.7 ± 10.2, 52.2 ± 11.7 and 44.7 ± 5.4 % reduction in cell death. When 200 mmol L-1 irinotecan was incubated for 72 hours with 100 mmol L-1 dexrazoxane, losartan and diltiazem, respectively, a 27.7 ± 6.9, 25.6 ± 5.1, and 19.1 ± 2.3 % reduction in cell death was observed. Our data suggests that losartan and diltiazem were as effective as dexrazoxane in protecting the cells against irinotecan- and doxorubicin-induced cell toxicity. These findings offer potential uses of anti- -ischemic drugs for ablation of cytotoxicity in response to mitochondrial injury, thereby improving patient outcomes and reducing health-care costs.
